#orly has a "follows ACL" and a sync spider that stays very up to date, it whitelists all your follows, and automatically searches the events for relays and searches for events from them that it doesn't have, and syncs. within about 5 seconds after starting it up, it updates everything it can find.
it was specifically designed to be a personal relay, my first purpose with orly has been that. it has many more production-oriented features now, but the personal relay use case is my highest priority.
